The True Cost of International School Fees in Portugal (2026)
What the brochures don't tell you — a full cost breakdown from real families
The headline annual fees for international schools in Portugal range from €12,000 to €32,000. But the total cost of education almost always exceeds those figures. Here is what Raising Kids in Portugal's data from 200+ families reveals about the all-in cost.
1. Registration & application fees
Every school charges a one-time registration fee ranging from €500 (CAISL) to €3,000 (TASIS Portugal). Many also require a non-refundable deposit of 1 month's fees upon acceptance. Budget €1,500–4,000 additional in the first year.
2. Transport, uniforms, and extras
School transport for families living more than 5 km from campus typically costs €2,000–4,000 per year (return journeys). Uniforms are €300–600 per child for the full kit. Lunch programmes add €800–1,500 per year. Extra-curriculars (music, sport, drama) run €500–2,000 depending on activity level. Our conservative all-in estimate for one child at St. Julian's: €20,000–23,000 per year.
3. The cheapest and most expensive options
United Lisbon International School is currently the most accessible school on our list, with all-in costs starting closer to €14,000 per year for families living in Parque das Nações (no transport cost). TASIS Portugal in Sintra is the most expensive — with all-in costs for a family of two children exceeding €55,000–60,000 per year. Both schools offer merit-based bursaries; ask directly at enquiry stage.
